And what many people (depressingly) don't realize, is that dynamic typing (or OO boxing) is NOT needed to achieve that. I was actually impressed with that slide, too, but for a different reason: I've come across need for a function like argmin on occasion, but I didn't know it existed (Don't recall if it was actually in D, may have been another language I was using). That really is a fantastically useful function.
